GAS-BURNER zenr'rnn.

Specification of Letters Patent. Patented Aug, 24, 1915.

Application filed July 10, 1914. Serial No. 850,138.

To all whom it may concern:

Be it known that I, Fnnnnmcn ANDREAS, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Gas-Burner lgniters, of which the following is a specification.

This invention'relates to improvements in gas-burner igniters' and has for its object to provide a cheap, efiicient, simple, and neat device of the character described,which may be attached to a gas-stove in place of the ordinary cock thereon without changing the design of the front of the stove and the parts thereof or altering the arrangement of the manifold or other feed-pipe, and without making additional holes therein.

A further object of the present invention is to provide an auxiliary igniter of cheap and simple construction whereby an unlighted burner on a gas-stove may be ig-' nited from a lighted burner by merely turning on the cock of the unlighted burner.

Further, the present invention resides in the combination and'arrangement of parts described in this specification and set forth in the claims.

In the accompanying drawing forming part of this specification wherein like numbers of reference denote like parts wherever they occur, Figure 1 is a diagrammatical view of a plurality of gas-burners showing the apparatus embodying the present invention in connection therewith; Fig. 2 is a plan view of the igniter of this invention dctached from a burner; Fig. 3 is a side elevation of Fig. 2; Fig. 4 is a sectional view on the line 4 4, Fig. 2, showing the device of Fig. ,2 connected to a gas-supply pipe and a burner and showing the gas-cock in open position; Fig. 5 is a side elevation of the plug of the cock; Fig. 6 is a perspective view of the auxiliary igniter of this invention; Fig. 7 is a transverse sectional view of the auxiliary igniter and of the part of a burner; connected therewith; and Fig. 8 is a diagrammatical view of a plurality ofgasburners, showing an alternate arrangement of the auxiliary igniters.

The device of this invention consists preferably of a plug-cock 1 of the usual construction, except as hereinafter described. said cock having its plug 2 revolubly seated in valveseat 3 in casing 4 and held in place therein by any suitable means, such, for instance, as the spring 5 as shown in the drawings. Plug extension 6 is hollow, the hollow portion 7 extending the length of said plug extension and communicating with transverse passage 8 of said plug. Plug 2 is so constructed that gas may constantly be supplied to said hollow portion 7 through said plug-cock, this object being preferably attained by means of a groove 9 upon plug 2 from the passage 8 to by-pass port 10, which port 10 communicates with the passage 8, so that when plug 2 is revolved in its seat 3 in the direction of said groove 9 toward and to closed position with reference to the outlet 11 of said cock, gas will continue to flow to said hollow portion along said groove and through said passage 8 and said port 10.

Plug extension 6 bears a perforated pilot light nipple 12 at the end adjacent to said plug '2, said pilot-light nipple having a perforation 13 communicating with hollow portion 7 and being preferably provided with aregulating means in said perforation, such, for instance, as screw 11 to re ulate the flow of gas from hollow portion light vent 15, which vent communicates with to pilotperforation 13 and directs the flame of said pilot light toward igniter jet 16, which jet is borne by said plug extension and is provided with a perforation 17 for the emission of gas supplied thereto as hereinafter described. Intermediate said igniter jet and said pilot-light nipple, there is preferably a perforated nipple 18, the perforation 19 of said intermediate nipple 18 being adapted to issue gas supplied thereto as hereinafter described, the purpose of said intermediate perforated nipple being that gas issuing therefrom may be ignited by said pilot-light thus bridging the flame from said light to gas issuing from said igniter jet. Perfora tion 19 is preferably relatively smaller than perforation 17 for the reason that it is desirable that only sufficient gas issue therefrom to communicate flame from said pilotlight to said igniter jet, the flame from said ignlter jet being necessarily larger for the purpose of this invention hereinafter described. Also, intermediate nipple 18 is preferably shorter than either pilot-light nipple 12 or igniter jet 16 for the purpose, for instance, to facilitate ignition of said tion 7 b as bridging flame by causing the gas issuing from said shorter nipple to cross the path of direction of the flameof' said pilot-light.

A Valve 20 is provided within hollow portion'7 to control the flow of gas toigniter jet 16 and to intermediatenipple 18, said valve 20 and its associated parts being pref-.

erably constructed as hereinafter described.

A hollow bushing 21 open at both ends, is provided at its 1nner end with a valveseat 22, said valve-seat being adapted to seat therein said valve 20 which is preferably a conical valve and which bears a valve-stem 23 extending outward slidably through and beyond the outer end of said bushing 21 and terminates preferably with a button 25 or the like for unseating said valve 20, which v alve is normally held in closed or seated position preferably by means of a spring 26 supported in said hollow portion 7 upon shoulder 27 or the like and pressing against said valve 20 when said bushing 21 is in position within hollow portion 7 as hereinafter described. Button 25 or the like provides a convenient means for manipuating said valve to unseat same, and, also, provides a means for limiting the inward motion of valve-stem 23 by striking against a cap 28 or the like with which bushing 21 when button 25 is depressed and valve 20 is thereby unseated and opened, gas admitted to hollow portion29 of bushing 21 is substantially prevented from escaping at the outer end of said bushing. Bushing 21 is adapted to fit into hollow portion 7 and to extend therein beyond igniter jet 16 and its perforation 17 and beyond intermediate nipple 18 and its perforation 19, but said bushing 21 must not extend so far into hollow'portion 7 as to obstruct the communication of perforation 13 of pilot-light nipple 12 with said hollow portion. To permit perforation 17 of igniter jet 16 and perforation 19 of intermediate nipple 18 to communicate with hollow portion 29 of bushing 21, said bushing is preferably provided with two holes 30 and 31, said holes bein adapted to register respectively with per orations 17 and 19 when said bushing is in place in said hollow portion 7, bushing 21 being preferablv screwed in'place in said hollow pormeans of screw-threads on the interior 0 said hollow portion 7 coiiperating with screw-threads. on the outer side of said bushing 21.

Ahousing 34 is preferably provided to inclose the assembled parts hereinabove described, said housing being preferably constructed of two vertically divided 'parts, as shown in the drawing, the edges of one part bearing grooves 35 or the like adapted to engage the adjacent edges of the other part so that when said housing is placed about said assembled parts and screw-bolt 36 or the like is in place for uniting the two parts ofv said housing, said two parts will be firmly held together. Housing 34 isprovided with an appropriate opening 37 through which button 25 and the adjacent end of valve-stem 23 preferably extend, and,

also, through which opening handle 38 of said plug-cock 1 extends for conveniently operating said plug-cock. Shoulders 39 or the like borne by said opening 37 are preferably provided to limit the movement of handle 38 substantially to prevent its movement beyond full closed position of said cock in one direction and beyond substantially full-open position of said'cock in the opposite direction. An opening 40 is provided in housing 34, said opening being adapted to permit egress of flame from igniter-jet 16 for the purpose of this inven tion, and one or more holes, like holes 41, may be provided in said housing to facilitate the passage of air to flame of said pilotlight and the like'within said housing and to assist in keeping said casing and said assembled parts cool. The pilot-light at saidpilot-light nipple 12 is protected by said casing so that the very small flame issuing therefrom may not be extinguished by gusts of wind and the like. v

The above-described device is attached to a gas-stove (preferably at the most frequently used burner thereof) in place of the ordinary cock, such, for instance, as an ordinary plug-cock, and is so constructed that it is not necessary to drill additional holes for its connection to a gas-stove, and, also, its construction is such that the neat appearance of the stove-front is not marred, for the plug-cock bearing the device of this invention above described is constructed so that its handle 38 is substantially in line with the handles of the ordinary plug-cocks on the stove to which this device is attached as shown-in Fig. 1.

For the purpose of illustration, a gas-stove having four burners, 42, 43, 44 and 45 has one burner 42 provided with plug-cock 1 bearing the above-described igniter device of this invention, and the remaining burners 43, 4-4 and 45 are provided with ordinary cocks 46. For the purpose of conveniently communicating flame from burner 42 ignited by means of the above-described device to an adjacent burner 43, 44, or 45, an auxiliary igniten iiis provided, said igniter consisting preferably of a hollow tube closed. at both ends, there being preferably a spud 48 adjacent each end of said tube, each of saidspuds being adapted to fit inopening 49 in said tube and having openings 50 adapted to communicate with the channel of said tube 17. Said tube 17 bears a slot 51 or the like running preferably along the entire length of said tube. Theend of one of said spuds 48 protruding from its attached tube 47 is inserted in an appropriate opening 52 therefor in burner 12 and the end of the other spud protruding from that tube to which said spud is attached is inserted in an appro-' priate opening 52 in adjacent burner 43 and thus the two burners l2 and 13 are connected together by means of tube 17 and communicatewith each other through the channel of tube 47, and burner 12 is similarly connected to burner -14 and to burner 45. Flame from ignited burner 12 will ignite burner 13 by means of gas issuing from said burner and flowing toward said flame through tube $7, said flame igniting said gas and traveling along slot 51 of said tube to said burner 43. Similarly, burners 4t and 15 may be ignited.

Instead of connecting the burners of a gas-stove as hereinabove described and illustrated, the .burners may be connected in series by means of auxiliary igniters 47, as shown in Fig. 8,

The operation of the main igniter device of this invention borne by plug-cock 1, which is connected to burner 4-2 is as follows: Plug-cock 1 is normally in closed position (shown in the full line position of handle 38 in Fig. 2), with reference to the flow of gas to burner 12, in which position gas is permitted to flow from manifold supply pipe through port 10, groove 9, and passage 8 connected therewith, into hollow portion 7 and out through perforation 13 and vent 15 to feed the flame of the pilot light ignited at said vent, which flame may be regulated by adjusting screw 14 adapted to regulate the flow of gas through vent 15. Whenit is desired to admit gas to burner 12., plug-cockd is turned by turning handle 88 from full line position shown in Fig. 2 to the dotted line. position shown in said figure, plug 2 being revolved in its valve-seat 3 in the direction'of' groove 9 from by-pass port 10 to passage 8 connected therewith, so that during said movement of said plug gas may continue to flow into hollow portion 7 to feed the pilot-light at pilot-light nipple 12.

d When cock l is in open position (shown by dotted line position of handle 3% in Fig. 2) for admitting gas to burner 42, igniter jet 16 will be facing-burner42 in proper position for shooting flame from gas issuing from perforation 17 in the direction of said burner 42. To admit gas into bushing 21, button 25 is depressed to unseat valve 20 portion 7: will enter hollow portion 29 of bushingQl and issue outward through perforation 19 in intermediate nipple l8 and through perforation 17 of igniter' jet 16. As gas issuing from intermediate nipple 18 comes in contact with the flame of the pilotlight from nipple 12, said flame being-directed toward said intermediate nipple and toward-said igniter jet by means of vent 15 as hereinabove described, said gas is ignited and communicates flame to gas issuing with some force through the larger perforation of igniter jet 16, which flame shoots toward burner 42 and ignites gas issuing from said burner, whereuponJbutton 25 is released};

valve 20 is reseated in closed position, the" flow of gas to said lgniter jet and to said intermediate nipple is cut off, the flame from igniter jet 16 and intermediate nipple 18 extinguished while the pilot-light at pilot-light nipple 12 continues to burn.

When it is desired to ignite burner 43 from burner 42 connected therewith by means of auxiliary igniter 17, it is merely necessary to open gas supply cook 16 (of the ordinary construction) to admit gas to its connected burner 4:3, whereupon flame from ignited burner 12 will travel along slot 51 of tube 17 as gas flows into said tube from said burner 43 and the gas issuing from said burner t3 will be ignited. In a similar manner, burner 44 may be lighted from burner -12, and, also, burner 45 may be lighted from burner 42.
